Helsinki abandons plans for ash scattering site on Vantaa River over endangered mussel

Helsinki has scrapped plans to create a site for scattering cremated remains along the Vantaa River due to environmental concerns, particularly risks to the endangered thick-shelled river mussel, Yle reports.

The city had proposed establishing an accessible scattering location near Vanhankaupunginkoski in Kustaa Adolfin Park, where flowing water would carry ashes to sea. However, officials determined that some ash could settle on the riverbed, with unknown effects on aquatic life.

“We’re applying the precautionary principle,” said Vili Tuomisto, team leader for Helsinki’s marine environment unit, citing the presence of the protected mussel species. He noted that low water levels in summer could further concentrate ash deposits.

The city now plans to open its first easily accessible scattering site—without requiring a boat—at the Herttoniemi breakwater, potentially by the end of 2026. The location offers strong transport links, including metro access. Two additional coastal sites, one each in eastern and western Helsinki, are also under consideration.

Tuomisto said residents had inquired about the Kustaa Adolfin Park site following last summer’s announcement, with some facing urgent needs to fulfill final wishes. Others raised environmental concerns, prompting calls for thorough impact studies.

Suomenlinna remains unlikely to host a scattering site in the near future, as decisions rest with the governing board of the UNESCO-listed fortress. The Vantaa River section in Helsinki is part of the Natura 2000 network of protected areas.
